Ta'all'tvhom it mag concern: I

Be it known that 1, JAMES ILNORTHROP, of Hopedale; county OfWOlCGster, and State of Massachusetts, have invented an Improve I 5 ment in Thread-Guides, of which the follow,

ing description, in connection with the accompan'ying drawings, is 'aspecification, like letterse on the drawings representing like parts.

- This invention hast-or its object the pro- 10 duetion of a new, and improved thread or yarn guide or clea er ct cheap and; simple structu're, ca.pab1e of. easy and accurate adj 11stsnent-{ahdwhich can be cleaned with ease ""and without injury to the various partsof the;

5 The rccessed part o'f the fixed jaw A, adjacent the shoulder 0% of the movable jaw, prevents undue movement of the latter when opened, andflthe' shoulder or projection 0 serves also to prevent the' thread or yarn from get-tin g out between-theja-ws at that end thereoli I vary the'sp'ace between the jaws accord ing to the size of the thread or 'yarn, by means of the. adj usting-stu'd Z), for when it is turned,

itsend 1) restiiv 8111.11 in the enlar ement.

D b b afithe eccentricity of the body I) will n ise or lower. the jaw- C, thus varyingthe space between the faces of the two jaws. This is-ef-' fe'ctedwithout disturbi'ng in the least the clamp whichholdsthe'entire device in posi- -tion.- "l v I, A set-screw b holds-the adjusting-stud b in adjusted position, andi'when the set screw is loosened the stud can 'be 'rotated-by'a suitable kc or wrench: applied to its head 11 Tocl an the faces of the aws, it-is only necessaryto press the jaw C out of alinernent withthe oppo eing'jaw, when both jaws can eoaeee be quickly and easily wiped ofii with a cloth or piece of waste. Upon removing the hand the weight 0' causes the pivoted jaw to swing: back to its proper position.

The advantages which I secure by my improved construction are numerous. By it I am enabled to quiekl and easily wipe acuunnlations of lint and the like from the jaws, as described,without rougheniug the same by scraping, and can accomplish this without in any wav interfering with the adjustment of the jaws or with the clamp which fastens the devicetotherod. lamalsoenabled'tochange the adjustment without in any way interfering: with the clamp.

i-inother important advantage of my construction is that it renders impossible the changing" of the vertical distance between the planes of the opposing faces of the jaws by the insertion of a match orother foreign substance, which is often done by the attendant in order that the knots may run through clear without breaking the thread or yarn, while it does at the same time permitthe operator to move the pivoted jaw sulliciently to keep the faces clean and smooth.

i have thus explained the nature of myinvcniion and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all the modes of its use.

Having fully described my invention, what I claim as new, and desire to secure byLettcrs Patent, is

1. in a yarn-guide, the combination with ii .cd jaw, of a movable jaw, a pivotal concetion between them, and means on said pivotal connection to adjust the movable jaw with relation to the fixed jaw.

i. in a varn-guidc the combination with a 1d jaw, of a movable jaw pivoted thereto n'ovided with means serving to adjust the pivoted jaw with relation to the fixed jaw.

ii. in a yarn-guide, the combination witha lined jaw, of an opposing jaw adapted to be moved transversely to said fixed jaw, and a means oi. a rotatable stud, said stud being rotatable support upon which the movable jaw 's pivotally mounted, rotation of said support varying the distance l ;twcen the jaws in a plane substantially pc rrcndicular to the plane of said transverse movement.

4-. In a yarn-guide, a fixed jaw, a movable jaw pivoted to move transvers-; thereto, means to attach the yarn-guide to l 5 support, independl ,t means to move the mmablcjaw bodily toward or from the llXOll ja iv, the movable jaw having a shoulder to limit its outward movement, and means to keep the iaws normally in aiinen'ientwith each other.

' 5. In a yarn-guide, a lined jaw, an eccentric adjusting-stud, and a movable jaw pivoted on said stud.

6. In a yarn-guide, a fixed jaw, a movable jaw l'lOllllltlly in alinement with. the lined jaw, whereby movement oi? one jaw will not inateriall v change the width. of the space between the jaws while exposing the edge of the movable jaw to be readily cleaned, an cccentric pivot upon which the movable jaw is mounted, and means to normally retain said jaws in alinement.

7. In a yarn-guide, a iisied aw, an cc itric adjusting-stud mounted parallel thereto and provided with a shoulder, a weighted movable jaw pivoted on said stud and held thereon by the said shoulder, and means to clamp the stud. in adjusted position.

8. In a yarn-guide, two jaws, an eccentric pivotal support for one 0t them, whereby said jaws have an operative relation to each other to present a slot of definite width between them by which to clean a strand of yarn passed thercthrough, and means to permit a restricted. movement of one relatively to the other, without appreciably changin the width of the slot between them.

In testimony whereof I have signed. my name to this specification in the presence of two subscribing witnesses.

AMES II. NORTIIROP.
